I make a habit of checking back to source when quoting, in part because I have come across academics who misquote (sometimes, it seems, with intent... but very hard to prove) and others who blindly quote them in their turn, so all sorts of BS is perpetuated in 'the academy', and eventually makes its way out into the consciousness of the wider public.
I always approach academic work by unknowns with great caution, until I have worked out if they're trustworthy (source correctly, get their quotes right or - if scientists - are clear about the limitations of their experiments).
Basically, I am cynical, and would expect a judge, of all people, to be cynical too.
